Dating a non Jewish guy in secret

I’ve been dating my non-Jewish boyfriend for almost 3 years, and my parents or family don’t know a thing. My parents aren’t super religious, but they are orthodox and very cultural and have expressed many times to me that they want me to date/marry only Jewish guys. I always avoided non-Jewish guys, but I’m genuinely in love with my boyfriend and have never felt such a strong connection and comparability with a guy before. I can’t imagine a life without him, and he is super understanding about the situation since I’ve had to hide him from my family for the past few years.

Does anyone have advice? I I don’t understand the problem and why we have to be so controlled of who we end up and fall in love with. I just don’t know how to ever bring this up to my family, and I’m scared shitless about their reaction. This whole situation highly stresses me out and makes me depressed, cause I feel like I’ll never be accepted and they’ll be super disappointed. I’m constantly asked who and if I’m dating, and I’ve just been lying to them for years.

Thanks in advance.
